BACKGROUND OF THE INVENTIONS

1. Field of the Inventions

This invention relates generally to accessories for communicationdevices (e.g., mobile telephones, mobile texting devices, electronic paddevices, laptop computers, desktop computers, gaming devices, and/ordevices capable of linking electronically to another device or to anetwork such as the Internet, etc.), and specifically to removablefunctional components for communication devices.

2. Description of the Related Art

In recent years, many advances in computer networking and processingtechnology have made it possible for communication devices to includecameras that permit users to capture images. In many cases, these imagescan be stored, processed, and transmitted. However, there are manydesign constraints on onboard cameras in communication devices that canlimit the weight, size, expense, shape, adjustability, and overallquality of the lensing systems of such cameras. Consequently, manycameras in communications devices are inadequate for a wide variety ofphotographic needs and may produce poor quality photographic images.These deficiencies cannot be addressed by existing modular or detachablelensing systems for use with conventional film or digital cameras due tosignificant differences between such lensing systems and communicationdevices, including incompatibilities in attachment structures, weight,optics, size, transportation, storage, ergonomics, and/or portability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following detailed description is now directed to certain specificexamples of embodiments of the disclosure. In this description,reference is made to the drawings wherein like parts are designated withlike numerals throughout the description and the drawings. Theinventions are not limited to the examples expressly illustrated ordescribed in this specification.

Referring to FIGS. 1A-1I, an example of a removably attachable lenscomponent 110 is illustrated in many different views. In someembodiments, as illustrated, the lens component 110 can generallycomprise a retainer portion 112 and a lens portion 114. The retainerportion 112 is generally configured to be removably attachable to acommunication device such that the lens portion 114 can be positioned ina region generally covering or near an onboard camera lens in thecommunication device to enable the lens portion 114 to cooperateoptically with the onboard camera, to provide optical enhancements,improvements, modifications, and/or alternatives. In some embodiments,as illustrated, the retainer portion 112 is shaped so as to attach tothe communication device in a region and in a manner that permits a userto see all or virtually all of a viewing portion 131 of thecommunication device without obstruction or without appreciableobstruction.

For example, the retainer portion 112 can comprise a channel 116 with aplurality of sidewalls 118. The width of the channel 116, e.g., thedistance between the respective sidewalls 118, can be configured to begenerally complimentary to the thickness of a portion of thecommunication device(s) on which the retainer portion 112 is configuredto attach. In some embodiments, the natural width of the channel 116 isapproximately the same size or slightly smaller than the thickness of acorner, such as an upper corner, of the outside housing of acommunication device near the light aperture of the onboard camera ofthe communication device.

In some embodiments, as illustrated, one or more of the plurality ofwalls 118 can have a curvilinear shape 119 along one or more edges topermit the retainer portion 112 to provide increased distance of contactalong the edge of the communication device while diminishing the areaacross a transverse surface of the device that is obstructed by theretainer portion 112. For example, in some embodiments, as illustrated,the curvilinear shape along one or more edges of the walls 118 permitsthe retainer portion 112 to extend along and attach to at least aportion of two generally converging or generally perpendicular outeredges or sides of a communication device that is approximately as wideas the lens portion 114, while diminishing the amount of space on thefront of the device that is blocked. In the example shown in FIGS.1A-1I, the curvilinear shape of the edge of the walls 118 can avoid oromit a lower pointed or sharp corner that may otherwise extend into andobstruct the viewing portion of the communication device. In someembodiments, the retainer does not appreciably block or obstruct theviewing surface, as shown in FIG. 2B.

All or part of the retainer portion 112, such as one or more of theplurality of walls 118, can be made of a material (e.g., a polymer or asilicone) that is sufficiently flexible to permit deformation (e.g.,compression, bending, or stretching) of one or more walls 118, so thatthe channel 116 can be temporarily widened while sliding the lenscomponent 110 onto a communication device, but at least a portion of oneor more of the walls 118 can be sufficiently stiff, rigid, or resilientto urge one or more of the plurality of walls 118 to return to itsoriginal position and thereby exert a gripping force against a portionof the communication device. The material of the retainer portion 112,especially the region on the inner side of the walls 118 within thechannel 116, can also be tacky or somewhat slide resistant to enhancethe gripping of the retainer portion 112 to the communication device. Insome embodiments, the gripping force and/or slide resistance can reduceor eliminate the need to attach a permanent or temporary mountingcomponent to the communication device. For example, the lens component110 can be repeatedly attached to and removed from a communicationdevice without requiring (though not prohibiting) installation on thecommunication device of a separate permanently or semi-permanentlyattached mounting component such as a bracket, magnet, adhesive, orother fastening component, thereby providing ease of installation whilepreserving the original overall shape, appearance, functionality,compatibility (e.g., with other communication devices or cases), and/orfeel of the communication device when the lens component is removed.

The retainer portion 112 can also comprise an upper wall 120 that can beshaped in some embodiments to generally correspond to the shape of oneor more edges of a communication device. As illustrated, the upper wall120 has a generally curvilinear shape with a rounded corner 122. Theretainer portion 114 can also include one or more internal surfacecontours 124 configured to generally avoid interference with one or moreexternal features on a communication device. For example, asillustrated, the channel 116 can include a surface contour 124 in thefoam of a groove to avoid interference or inadvertent contact with abutton or other feature on a communication device when the lenscomponent 110 is attached to the communication device. As illustrated,the sidewalls 118 of the retainer 112 can comprise one or more generallypointed or angular regions 129.

In some embodiments, as illustrated, the retainer portion 112 can beconfigured to grip two nonparallel sides of a communication device. Forexample, the retainer portion 112 can contact at least a first generallyvertical side or edge surface 133 of a communication device and at leasta second generally horizontal and generally orthogonal side or edgesurface 134 of a communication device (e.g., the lateral side and thetop side of the communication device) at the same time during use. Insome embodiments, this contact by multiple generally perpendicular edgesor surfaces permits repeatable adequately precise placement of theretainer portion 112 in a single attachment motion without requiringuser adjustment of the location or structure of the retainer portion 112during attachment. In some embodiments, two or more contacting surfacesin the retainer portion 112 can converge at an upper corner having arounded external surface. In some embodiments, as illustrated, theretainer portion 112 is substantially smaller than the communicationdevice to which it is configured to attach, or even substantiallysmaller than the viewing portion of the communication device to which itis configured to attach. In some embodiments, a retainer can beconfigured to contact only one side or edge (e.g., the generallyvertical or the generally horizontal side or edge), such as bycontacting both the front and rear surface of such side of edge butwithout also requiring contact with another side or edge. An example ofsuch an embodiment can generally be formed from a retainer portion witha general U-shape comprising an upper wall, two side walls, and anopening on each side of the side walls.

In some embodiments, the retainer portion 112 can permit the lenscomponent 110 to be attached to a communication device without requiringnon-stock mounts on the communication device and without requiringdynamic mounts on the retainer portion 112 itself (e.g. fasteners,screws, adjustable clamps, etc.). Thus, a user can attach the lenscomponent 110 to a corner of a communication device by simply slidingit, for example, onto the corner of the communication device, and canremove it by simply pulling it off, without requiring user adjustmentduring attachment. In some embodiments, as illustrated, the lenscomponent 110 can remain on the communication device by way of afriction fit. The attachment to the communication device can avoid aresidue deposit from adhesive, scratches to the exterior surface, orother damage or alteration of the communication device. In someembodiments, the retainer portion can be sufficiently wide and/or longso that it is adapted to receive an end and/or side region (e.g., two ormore corners) of a communication device rather than merely one corner,and the other aspects of other embodiments disclosed herein can apply tosuch embodiments, including but not limited to the shape and materialsof construction and the accomplishment of a friction fit between theretainer portion and the end and/or side region of a communicationdevice.

The lens portion 114 generally comprises a transparent lens 128, whichis typically made of a glass or a polymer, and a securing structure 126.The securing structure 126 can be made of many different types ofmaterials or combinations of materials, such as metals (e.g., aluminumor steel) or plastics. The securing structure 126 can include agenerally wide-area opening for receiving the lens 128 and a generallynarrow-area region for attachment to the retainer portion 112. In someembodiments, the securing structure 126 and the retainer portion 112 canbe configured to slide or otherwise move with respect to each other in alimited manner to allow for adjustment of the position of the lens 128with respect to the onboard camera lens of a communication device (e.g.,for the purpose of addressing manufacturing tolerances in the locationof the onboard camera lenses in some communication devices). Asillustrated, the mechanism or structure for attachment or securement ofthe lens portion 114 to the retainer portion 112 can be separate fromand/or can operate independently of the mechanism or structure forattachment or securement of the retainer portion 112 to thecommunication device. In some embodiments, as illustrated, the outsidesurface of the securing structure 126 can taper inwardly from thelens-receiving region to the retainer-attaching region to diminish theamount of material used in manufacturing and to diminish the size andweight of the retainer lens portion 114. In some embodiments, the lenscomponent can be very small, such as less than or equal to about 2½inches or less than or equal to about 1½ inches across.

The lens 128 can include multiple lenses or lens components. In someembodiments (not shown), the lens component 110 can comprise morecomplex lensing systems, such as lensing systems in which the focallength of the lensing system can be manually or electronically adjusted,such as with a lever or rolling dial or with electronic or motorcontrol, which may be positioned between the lens 128 and the retainerportion 112. An electronic or motor control can be attached and adjustedusing software in the communication device, either by a wired orwireless connection to the mobile communication device. Otherspecialized lenses in the lensing system can include a telephoto lenssystems configured to enlarge images, wide-angle lenses, fish-eyelenses, macroscopic lenses, and microscopic lenses.

The lens 128 can also comprise coatings or other features to increasescratch resistance, diminish glare or reflection, or decrease or filterlight transmitted through the lens 128. The lens component 110 can alsoinclude a cover configured to be fitted over the lens 128 during storageand transportation. The lens component 110 can comprise other storageand transportation features, such as a quick-release or other attachmentstructure to enable the lens component 110 to be conveniently carried bya user on a standard accessory carried by a person, such as a key ring,belt loop, bracelet, necklace, or other easily accessible location whennot attached to a communication device. A collection or kit of differentlens components 110 with various lenses having different lens features,including those described herein, can be provided within a storage caseto address various photographic needs.

As illustrated in FIGS. 2A-2B and 3A-3B, the lens component 110 can bemoved into proximity with a communication device 130, 134 that includesan onboard camera 132. In some embodiments, a lens component 110 can besold or provided together as a system with the communication device 130,134. The communication devices 130, 134 shown in FIGS. 2A-2B and 3A-3Bare versions of the iPhone mobile phone sold by Apple, Inc. The lenscomponent 110 can be oriented so that the channel 116 is directeddownwardly in general alignment with an edge or corner of thecommunication device 130 on which the lens component 110 will be mountedand rotated so that the lens 128 will be generally aligned with theonboard camera 132. As the channel 116 contacts the edge or corner ofthe communication device 130, the channel 116 may expand slightly as thewalls 118 flex or bend outwardly. A restoring force produced by theretainer portion 112 can urge the walls 118 back toward their originalposition, which can help to retain the lens component 110 on thecommunication device 130 during use. The lens 128 can then temporarilyprovide an enlarged, better focused, clearer, or otherwise enhanced,altered, manipulable, or improved image for the onboard camera 132.

FIGS. 4A-4B and 5A-5B illustrate examples of lens components 200, 202configured to be used on tablet-type communication devices 204, 206. Inthe illustrated examples, the communication device 204 is an iPadcommunication device sold by Apple, Inc., and the communication device206 is a Galaxy tablet sold by Samsung. The lens components 200, 202 caninclude various features and structures of the lens component 110illustrated and described in connection with FIGS. 1A-1I. In someembodiments, as illustrated in FIGS. 4A-B and 5A-5B, the lens components204, 206 can include a retainer portion 208 with walls 210, 212 ofdifferent sizes and lengths. A longer or wider-area wall 212 can beprovided on a side of the retainer portion 208 that is configured tosuspend the lens 128 in front of the camera 132, while a shorter orsmaller-area wall 210 can be provided on a side of the retainer portion208 that is configured to extend over a portion of the surface on whichthe viewing portion of the communication device 204, 206 is located. Theretainer portion 208 can be configured to securely attach the lenscomponents 200, 202 while diminishing or eliminating obstruction of theviewing portion. An aperture or other functional access region 216 canbe provided in the retainer portion 208 to permit access to controls orother interaction structures on the communication devices 204, 206 whenthe lens components 200, 202 are attached.

FIGS. 6A-6B illustrate an example of a lens component 302 with aretainer portion 308 that comprises a plurality of attachment arms 304that include attachment structures, such as hook portions 306, that canpartially or completely overhang on a portion of a communication device306 or that are oriented in a generally transverse direction to the mainportion of the attachment arms 304. As illustrated, the attachment arms304 can be generally tapered from a central, wider portion to aperipheral, narrower portion to provide sufficient structural rigidityand retaining force. The lens component 302 can include the variousfeatures of the other lens components 110, 200 described herein. Thecommunication device illustrated in FIGS. 6A-6B is an EVO communicationdevice sold by HTC Corporation. The attachment arms 304 can assist inattaching the lens component 302 to a device, such as the EVO device, inwhich the camera 310 is not positioned near a corner of the device.

FIGS. 7A-7I illustrate several views of an example of a lens component400 in which a plurality of lenses 402, 404 can be attached to the sameretainer portion 406. In this example, the user can have at least twodifferent options for the type of lens to use in a particularphotographic application. For example, one of the lenses 402, 404 canprovide a wide-angle view and another one of the lenses 402, 404 canprovide a fish-eye view. Many other lens options are possible. Forexample, one or more lenses can be provided with different colorfiltering capabilities, different light attenuation capabilities,different lens coatings (such as anti-reflection coatings), anddifferences in other optical properties to provide multiple useroptions. Different lenses can include any combinations of these or otheroptical features. The retainer portion 406 can include various featuresof the other retainer portions illustrated and described herein.

FIGS. 8A-8I and 9A-9E illustrate several views of an example of a lenscomponent 400 a that is similar or identical in many ways to lenscomponent 400 in FIGS. 7A-7I. Lens component 400 a includes a channel416 for receiving a portion of a communication device. The channel 416includes an attachment-facilitating surface 418. In the illustratedexample, the attachment-facilitating surface 418 comprises an inwardlycurved (e.g., sloped or slanted) surface positioned along the outer edgeor slotted opening of the channel 416. In some embodiments, theattachment-facilitating surface 418 can be positioned at or near anouter edge of the channel 416. As illustrated, theattachment-facilitating surface can be thinner near the edge and cangradually become thicker as it progresses further into the channel 416.

As the lens component 400 a is moved into an attachment position on acommunication device, the attachment-facilitating surface 418 canprovide an initial contact region or opening 420 a (see, e.g., FIGS. 8Gand 8H) near the outer edge 422 that is effectively wider to facilitateproper orientation and attachment of the device by a user, and anarrower second region 420 b further within the channel 416 (or furtherfrom the edge of the lens component 400 a), thereby providing a moresecure attachment surface as the lens component 400 a is moved furtheronto the attachment region of the communication device. In someembodiments, as illustrated, the width of the channel 416 can changebetween the initial contact region 420 a and the second region 420 b ina smooth, gradual, and/or curvilinear manner. Some embodiments caninclude many other types of shapes. For example, theattachment-facilitating surface 418 can include a discontinuous surfaceor a series of discrete ramps, protrusions, or grooves. Anattachment-facilitating surface 418 can be included on any embodiment ofa lens component and is not limited to use in the lens component 400 aas illustrated in FIGS. 8A-8I and 9A-9E.

As illustrated in FIGS. 10A-10C, the user can select which of theplurality of lenses 402, 404 to position in front of the camera 132 ofthe communication device 134 to achieve a desired photographic affect.In FIG. 10A, the lens component 400 is moved into an attachment positionon a communication device 134 such that a first (e.g., smaller-diameter)lens 402 is positioned in front of the onboard camera lens 132 and a(e.g., second larger-diameter) lens 404 is positioned on an oppositeside of the communication device 134. In this orientation, thesmaller-diameter lens 402 is operative and the larger-diameter lens 404is not operative. In FIG. 10B, the lens component 400 is removed fromthe communication device, rotated about a vertical axis (e.g.,approximately 180° in this example), and rotated about a horizontal axisto orient the channel 416 in general alignment with an attachmentsurface (e.g., a housing edge) of the communication device. In FIG. 10C,the lens component 400 is again advanced onto the communication device134 such that the larger-diameter lens 404 is positioned in front of theonboard camera lens 132 and the smaller-diameter lens 402 is positionedon an opposite side of the communication device 134. In thisorientation, the larger-diameter lens 404 is operative and thesmaller-diameter lens 402 is not operative. In some embodiments, thisconfiguration of a lens component 400 can conveniently permit multiplelens options without necessarily requiring the user to hold or storemultiple discreet lens components. In some embodiments, more than twolens types or features can be included in the lens component 400,thereby providing the user with many lens options.

FIGS. 11A-11F illustrate several views of an example of a lens component500 in which a lens 502 is attached to a retainer portion 504. The lenscomponent 500 can be attached to a communication device 134 in a mannersimilar to the lens components described above. When the user hasattached the lens component 500 to the communication device 134, theuser can adjust (e.g., tilt, swivel, or otherwise move) the lens 502with respect to the communication device 134 (e.g., azimuthally, alongthe lens's vertical axis, along the lens's horizontal axis, acombination of these adjustments, etc.). The user can shift or otherwisemove the lens 502 into a plurality of positions with respect to theretainer to diminish misalignment between the onboard lens in thecommunication device, or to change the viewing angle of the lens 502, orfor some other reasons. In some embodiments, the user can shift ofotherwise move the lens 502 into at least a first and a second position,or at least a first, a second, and a third position, or gradually acrossan adjustment zone. In some embodiments, this adjustment can form a void506 behind the lens portion 502. The ability to adjust the lens 502 withrespect to the communication device 134 can be advantageous inaddressing manufacturing differences or tolerances in the locationand/or alignment of the onboard camera lenses in some communicationdevices.

In some embodiments, the tilting of the lens 502 is facilitated by apivot (not shown) on the portion of the lens facing the communicationdevice 134. The lens 502 is positioned in a channel formed by sidewalls508 of the retainer portion 504. In FIG. 11A, the lens 502 is tilted tothe left with respect to the communication device 134 such that a void506 is formed between the rear of the lens 502 and a panel of theretainer portion 504 or the communication device 134 when attached, andthe exterior walls of the lens portion 502 are non-parallel with theadjacent interior, walls of the lens retainer portion 502. Asillustrated, the distance between the rear of the lens 502 and aninterior edge, line, or cross-sectional region 507 of the retainerportion 504 is greater on a first side 509 than on a second side 511. Inthis orientation, the lens 502 can compensate for an off-centeralignment of the onboard camera of the communication device 134. Forexample, in the adjusted orientation shown in FIG. 11A, the central axisof the lens portion 502 can be brought into general alignment with thecentral axis of the onboard camera lens 132. FIG. 11B illustrates thelens 502 in a neutral position with respect to the communication device134. In this orientation, the lens 502 need not compensate for anyoff-center alignment of the onboard camera of the communication device134. FIG. 11C illustrates the lens 502 tilted to the right with respectto the communication device 134, forming a void 506 in a manner similarto FIG. 11A. In this orientation, the lens 502 can compensate for adifference or off-center alignment or location of the onboard camera ofthe communication device 134.

In some embodiments, the tilting of the lens 502 is facilitated by aball and socket joint formed by a ball 510 on the portion of the lens502 facing the communication device 134 and a socket 512 in the retainerportion 504. This embodiment can generally function in a manner similarto the embodiment in FIGS. 11A-11C. The ball portion 510 can approximatethe shape of a generally oblate spheroid and can have one or more flator straight portions. The ball portion 510 can be, but is not requiredto be, generally spheroid. In the embodiment illustrated in FIGS.11D-11E, the portion facing the communication device 134 is generallystraight or flat. The ball 510 can be positioned within a socket 512with a generally complementary shape, facilitating rotation of the lens502 with respect to the retainer portion 502 and communication device134. In FIG. 11D, the lens 502 is tilted to the left with respect to thecommunication device 134 such that a void 506 is formed between the ball510 and socket 512 or the communication device 134. In this orientation,the lens 502 can compensate for miscorrespondence in the alignment orlocation of the onboard camera of the communication device 134. FIG. 11Eillustrates the lens 502 in a generally neutral position with respect tothe communication device in which at least one wall of the retainerportion 504 can be generally parallel with either or both of the frontor back surfaces of the lens portion 502. In this orientation, the lens502 need not compensate for any miscorrespondence in the alignment orlocation of the onboard camera of the communication device 134. FIG. 11Fillustrates the lens 502 tilted to the right with respect to thecommunication device 134, forming a void 506 in a manner similar to FIG.11D. In this orientation, the lens 502 can compensate formiscorrespondence in the alignment or location of the onboard camera ofthe communication device 134 or otherwise help to adjust the nature ofthe photographic image produced. In the illustrated examples of FIGS.11D-11F, at least one wall of the retainer portion 504 can be generallynon-parallel with either or both of the front or back surfaces of thelens portion 102. As illustrated, the user can appropriately adjust thelens portion 502 with respect to the lens retainer portion 504.

As shown in FIG. 12, the lens retainer portion 504 can include one ormore generally circular retaining walls 530 for receiving a lens portion502 in an adjustable manner. The retaining walls 530 can include one ormore apertures 535. A radially interior surface 537 of either or both ofthe apertures 535 can include a first adjustment structure, such as anadjustment channel 540 with a width and depth configured to receive asecond adjustment structure on the lens portion 502, such as a ridge orbump. In the illustrated example, the adjustment channel 540 can besubstantially smaller in width than the width of the interior surface537 of the aperture 535 to provide a relatively small amount ofrestricted movement of the lens portion 502. For example, in someembodiments, the width of the adjustment channel 540 can be less than orequal to about 1.5 mm, and the interior of the adjustment channel 540can be tapered or beveled toward a generally central portion or line toincrease the force required to move the lens portion 502 away from aneutral position. The width of the ridge or bump on the lens portion 502can be less than the width of the adjustment channel 540, such as lessthan or equal to about ¾ of the width of the adjustment channel 540. Thefirst and second adjustment structures can fit closely or tightlytogether (e.g., in a radial interference fit) while permitting limitedmovement when a force is applied by a user in opposition to frictionalforces between the adjustment structures. In this example, the lensportion 502 can be adjusted by a user to move with respect to the lensretainer portion 504 when moved in a deliberate manner, but the lensportion 502 and retaining portion 504 can generally remain in placeuntil another adjustment. In some embodiments, the amount of adjustmentcan be relatively small, such as greater than or equal to about 0.5degrees and/or less than or equal to about 2.5 degrees between theorientation of the central longitudinal axis of the lens portion 502 inthe original position as compared to the orientation of the centrallongitudinal axis of the lens portion 102 in the fully adjustedposition. In some embodiments, the lens portion 502 can be adjusted tovarious positions between (or outside of) these points or ranges. Theamount of movement between the rear surface of the lens portion 502 andthe lens retainer portion 504 can be relatively small as well, such asgreater than or equal to about 0.1 mm and/or less than or equal to about1.0 mm between the original orientation and the fully adjustedorientation.

As illustrated in FIGS. 13A-13C, the user can adjust the tilt of thelens 502 with respect to the communication device 134 to improve thealignment or other correspondence between the lens 502 and the onboardcamera of the communication device 134. In FIG. 13A, the lens 502 is ina neutral position with respect to the communication device 134. Theimage on the screen 560 of the communication device 134 is off-center tothe left, as evidenced by the leftward orientation of the vignettingwhich would normally be centered about the image. FIG. 13B shows theuser 590 tilting the lens 502 to the right to compensate for theoff-center image on the communication device 134. FIG. 13C illustratesthe corrected image, with the vignetting centered about the image eventhough the onboard camera of the communication device is not alignedproperly. In some embodiments, the tilt of the lens 502 can be adjustedwhile the user 590 is viewing a live image from the onboard camera onthe screen 560 of the communication device 134, providing real-timefeedback to the user about whether the correct adjustment is being made.

FIGS. 14A-14B illustrate two views of a lens component 600 with a lensportion 630 and a light-enhancing feature, such as a light pipe 610. Thelight pipe 610 can be mounted to the retainer portion 660 or to someother portion of the lens component 600. The light pipe 610 conveyslight from a light source, such as a flash, to an exit point 620 so thatit may illuminate the area to be photographed. In some embodiments, thelight pipe 610 is made from material which facilitates conveyance oflight from the flash to the area to be photographed. In someembodiments, the interior of the light pipe 610 is lined with materialwhich facilitates conveyance of light from the onboard flash to the areato be photographed. The position of the flash 650 on the communicationdevice 134 illustrated in FIGS. 14A-14B is close enough to the onboardcamera 132 that the lens component 600 generally covers or otherwiseobstructs the flash 650 when it is attached to the communication device134. In some circumstances, this may prevent light from the flash 650from enhancing photographs taken when the lens component 600 isattached. The light pipe 610 conveys the light from the flash 650 to theexit point 620, and from there the light travels normally to illuminatethe area in front of the camera.

In some embodiments, the light pipe 610, retainer portion 660, and/orsome other portion of the lens component 600 can be configured togenerally or entirely surround the flash 650 and/or other region fromwhich light emanates to inhibit or prevent undesirable light transfer orleakage outside of the pathway from the onboard flash into the lightpipe 610. Such an undesirable transfer or leakage may include light fromthe onboard flash moving into the rear side of the lens portion 630 ofthe lens component 600 or light from the onboard flash moving outside ofthe region between the retainer portion 660 of the lens component 600and the communication device.

In some embodiments, the retainer portion 660 or another component canbe formed from various materials, including polymers (e.g.,polycarbonate), metals (e.g., aluminum), etc., or some combinationthereof. For example, at least a portion of the retainer portion 660 canbe formed using a multi-step molding process, such as multi-shotinjection molding, inserting molding, or overmolding, and/or theretainer portion 660 can include a coating, such as an adhesive, paint,or deposited film, to provide a region on the interior and/or exteriorof the retainer portion 660 that has a different durometer or appearancethan another portion of the retainer portion 660. In some embodiments, aharder shell or exterior can be provided in conjunction with a softerinterior surface. For example, an interior region of the retainerportion 660 that is intended to be positioned in contact with the cornerof the communication device can comprise a surface that is softer and/ormore tacky than an exterior region or a supporting region of theretainer portion 660. In some embodiments, the softer or more tackysurface can provide an enhanced light seal by compressing against thecommunication device to inhibit or prevent light leakage.

FIGS. 15A-15B illustrate two views of a lens component 600 a with alight pipe 610 a. In many respects, the light pipe 610 a is similar oridentical to the light pipe 610 described above. The exit point 620 a ofthe light pipe 610 a can generally or completely surround the lens 630a, providing a generally ring-shaped flash. This can be particularlydesirable for use in macro (or close-up) photography. Thelight-enhancing feature can also be provided by a flash or other lightsource on the lens component 600, without requiring use or connectionwith an onboard flash.

In some embodiments, a light-enhancement feature can include anexternally attachable flash component connected to the lens component110 that can be selectively configured to be in electronic communicationwith the communication device (e.g., by way of a wireless protocol suchas the Bluetooth® protocol, or by way of a wired connection such as aUSB or serial connection, etc.). The flash can be powered by and/oractuated by the communication device. In some embodiments, the flash canpivot, tilt, or otherwise move with respect to the retainer portion 112to direct light as desired by the user.

In some embodiments, as illustrated and described herein, lenscomponents can include retainer portions with attachment structuresconfigured to be removably attached to communication devices, even whenthe communication devices themselves are generally smooth or flat and donot have corresponding attachment structures in the region near theonboard camera. In this way, the communication devices are not requiredto be permanently or temporarily modified, reconfigured, defaced, orotherwise altered in appearance to permit attachment of the lenscomponents. In some embodiments, this arrangement can permituninterrupted and unobstructed, normal use of the communication devicewhen the lens component is removed. However, in some embodiments,modifications to the communication devices may be useful or necessary toattach the lens components.

FIGS. 16A-16F illustrate views of a lens system 700. The lens system 700can include a lens component 702. The lens component 702 can be similarto other lens components described herein.

The first adaptor connection portion 712 can includea channel 714. The channel 714 can be sized and/or shaped to correspondto the size and/or shape of at least a portion of the communicationdevice 720, such that the adaptor 710 can slide over a portion (e.g. acorner) of the communication device 720, and be held in place on thecommunication device 720 (e.g., by way of a friction fit).

The adaptor 710 can further include a second adaptor connection portion716. The second adaptor connection portion 716 can be sized and/orshaped such that it is received within the channel 709 on the lenscomponent 702. The second adaptor connection portion 716 can include atleast one opening 718 to permit optical communication between the lens704, 706 and a corresponding onboard camera 722 on the communicationdevice 720.

The adaptor 710 and lens component 702 can be positioned such that thelens 704, 706 is positioned in a region generally covering or near theonboard camera 722 in the communication device 720 to enable the lens704, 706 to cooperate optically with the onboard camera, to provideoptical enhancements, improvements, modifications, and/or alternatives.In some embodiments, as illustrated, the adaptor 710 and lens component702 are shaped so as to attach to the communication device 720 in aregion and in a manner that permits a user to see a viewing portion ofthe communication device 720 without obstruction or without appreciateobstruction.

The lens component 702 can be removably attached to the adaptor 710 in avariety of manners. For example, the lens component 702 can be attachedsolely via a friction fit between the retainer portion 708 and thesecond adaptor connection portion 716. In some embodiments, the lenscomponent 702 can snap into place on top of the adaptor 710. Otherattachment options are also possible.

The adaptor 710 can allow the lens component 702 to be used with one ormore different communication devices. For example, the adaptor 710 canallow the lens component 702 to be used with a communication device thatis different in size, thickness, and/or shape than one that the lenscomponent 702 is typically designed for. For example, in someembodiments, the communication device 720 can comprise an iPod Touchdevice, manufactured by Apple, Inc., and another communication device134 can comprise an iPhone, also manufactured by Apple, Inc. The iPhoneis typically larger, and thicker, than the iPod Touch. If the lenscomponent 702 is designed and sized to specifically fit onto the iPhone,but not onto the iPod Touch, the user can conveniently and simply usethe adaptor 710 in order to use the lens component 702 with thecommunication device 720.
